Description

This is a 371 of PCT/JP93/01856 filed Dec. 22, 1993.

FIELD OF THE INVENTION

The present invention relates to novel heterocyclic derivatives and pest control agent.

BACKGROUND ARTS

Up till now, a number of insecticides and acaricides have been used for agricultural production, however, many of them do not satisfy enough such conditions as sufficient effectiveness on pests, no restriction in their use due to resistance problems raising against the agents, no phytotoxicity, no contamination in plant crops and less toxicity to humans, livestock and fishes. It is, therefore, intensively demanded to provide a chemical agent which can satisfy the aforementioned conditions and particularly safety requirements.

It is an object of the present invention to provide a chemical agent for controlling pests having firm effectiveness and usable to be safe.

The compounds similar to the compounds of the present invention have been disclosed as described hereinbelow, though their biological activities are not mentioned in those disclosures.

For the pest insects as exemplified above, the compounds of the present invention has all of excellent adulticidal, nymphcidal, larvicidal and ovicidal activities. Recently, a problem has been raised in the control of the pest insects, such as diamond back, planthoppers, leafhoppers, aphids, and plant mites, since these insects and mites have developed the resistance to insecticides, such as organophosphorus insecticides, carbamate insecticides and acaricides, whereby the activity of those insecticides and acaricides have been decreased. Therefore, a chemical which can be effective against such resistant insects and mites has been desired. The compound of the present invention has an excellent insecticidal and acaricidal activities not only against susceptible strains of those insects and mites but also against the resistant strains of those insect and mite to organophosphorus compounds, carbamate compounds, pyrethroid compounds and acaricides.

Some of the compounds of the present invention have excellent fungicidal activity against wide varieties of phytopathogenic fungi, which can be used for the control of various plant diseases attacking many of agricultural and horticultural crops, flowers, turf and pastures. As the preferable examples of the diseases to be controlled with such compounds, powdery mildew, downy mildew or scab on various crops can be exemplified.

Among the compounds of the present invention, I-43, I-44, I-125, I-335, I-337, I-340, II-10, II-27, V-7, V-17 and VI-3 are particularly effective against the diseases, such as powdery mildew, downy mildew or scab.

The chemical agent for controlling pests specified in the present invention contains a compound represented by the general formula �I! as its active component. The compound can be used for the control agent without formulating, however, it is normally used in a typical applicable form for agricultural chemicals, such as wettable powder, water soluble powder, dust formulation, emulsifiable concentrate, granular formulation, flowable formulation, etc. For additives and carriers when used for solid formulations, plant-origin powder, such as soybean powder and wheat flour, fine mineral powder, such as diatomaceous earth, apatite, gypsum, talc, bentonite and clay, and organic and inorganic materials, such as sodium benzoate, urea and Glauber's salt can be used.

For a solvent to be used in liquid formulations, vegetable oils, mineral oils, distillate fractions of petroleum, such as kerosene, xylene and solvent naphtha, cyclohexane, cyclohexanone, dimethylformamide, dimethylsulfoxide, trichloroethylene, methyl isobutyl ketone, water and the like can be used. In order to obtain homogeneous and stable liquid formulation, a surface active agent may be added to the formulation, if required. The wettable powder, the emulsifiable concentrate, the water soluble powder and the flowable formulation obtained as described above can be used after diluting them, respectively to a desired concentration of the suspension or emulsion. The dust and granular formulations obtained as described above can be used by spray directly to crop plants.

Although the compound of the present invention is sufficiently effective alone, it can also be used in a blend with various kinds of insecticides, acaricides, nematicides, fungicides and synergistic agents.

Test Example 2

Efficacy against two-spotted spider mites

17 female adults of organophosphorus acaricide-resistant two-spotted spider mites were inoculated on the first true leaf of French bean growing in 6.6 cm pot for 7 to 10 days after germination. Then the suspension of the wettable powder of the inventive compound prepared according to the recipe of the example 4 was adjusted to a concentration of 125 ppm with water to spray for the mites on the leaf. The mites were allowed to stand in a chamber maintained at 25.degree. C. and 65% R.H., then were removed on the third day after spraying. The eggs of the mites depositted during that period were examined on the 11th day after spraying, and the numbers of the mites which could grow up to the adult stage were checked to thereby determine the effectiveness of the inventive compound. The results are shown in Table 3. The effectiveness was calculated according to the following equation. ##EQU1##
